The test for Lactate Dehydrogenase (LDH) is a blood test that measures the levels of LDH enzyme in your blood. LDH is found in many tissues and organs throughout your body, including your heart, liver, kidneys, muscles, and red blood cells. LDH levels can rise in response to tissue damage, inflammation, or other medical conditions, so the test for LDH is often recommended by healthcare providers to help diagnose or monitor a range of conditions.
Here are some reasons why you may need to get the test for LDH:
To diagnose and monitor heart or liver damage: LDH levels can increase when there is damage to the heart or liver. Your healthcare provider may order an LDH test if you have symptoms such as chest pain, shortness of breath, abdominal pain, or jaundice.
To monitor cancer: LDH levels can be elevated in people with cancer, especially those with lymphoma or leukemia. An LDH test can help your healthcare provider monitor your cancer treatment and evaluate the effectiveness of the treatment.
To diagnose and monitor muscle damage: LDH levels can also increase when there is damage to your muscles. Your healthcare provider may order an LDH test if you have symptoms such as muscle pain, weakness, or cramping.
To diagnose and monitor anemia: LDH levels can be elevated in people with hemolytic anemia, a condition where red blood cells are destroyed too quickly. An LDH test can help your healthcare provider diagnose this type of anemia and monitor its treatment.
To diagnose and monitor infections: LDH levels can be elevated in people with infections such as pneumonia, meningitis, or sepsis. An LDH test can help your healthcare provider diagnose and monitor these infections.
Overall, the LDH test can provide important information about the health of your heart, liver, muscles, and blood cells, as well as help diagnose and monitor a range of medical conditions. If you have symptoms or concerns about any of the conditions mentioned above, it’s important to talk to your healthcare provider to determine if an LDH test is appropriate for you.
